That's older steppers for you, though, I suspect.
Maybe one of the closed-loop steppers from
Thanks to all who responded. I don’t think he is married to servos, it is just
that the system he has has an old stepper and it has never worked well, most
industrial machines he has in his shop have servos so he thought that would be
more reliable.

Huh. I've yet to have issues with Firefox on either Wheezy or Ubuntu 16.04
LTS. Perhaps one or more of your plugins have gang aft agly. Or perhaps one
of your config changes is causing issues
Try turning off all your plugins and trying again. If it works then bring
up your plugins one at a time
Greetings all;
Its a known fact that the default FF in an uptodate wheezy install is
badly bent, it not completely broken, or its javascript is.
So heres a chuckle for folks that like to do stuff the hard way:
Needing to buy the 7i76D and a high speed 1284 cable to interconnect it
to a 5i25

Exactly. And in my case it
I think the only reason to have a UPS on a machine is if you actually
wanted to run the machine after losing AC power. that case the UPS would
be sized to power the entire machine, motors and all.
If you are concerned about file system corruption on power failure, two
things can help (1) use a

I once worked on an old Sodick wire eroder. It had a large 12V battery
built in. But I can't remember to what extent the battery kept circuitry
alive in the event of a power fail.

I have done quite a lot of maintenance work on various industrial
machines. I can't think of even one machine I have worked on that had a
UPS fitted. I have seen a few with line conditioning circuitry where
they have particularly noisy supply. If power cuts are a regular
occurrence I suppose a

A userspace HAL component could record
The machine stops when the emergency button is pushed. The power to the
motors are cut and the programs stops at a line. The operator records
that line (or at least I do ) and then the job can be run from there or
the closest line that is not in a canned cycle or and incremental
command.
I’m intrigued by the “record the line number and then shut down” part. Is this
something that the user would do manually after noticing that the power was cut
or is this somehow automated?

I agree with Andy. I put my controllers on a UPS and then have a signal
that is wired through a drop-out relay that is also connected to the
emergency stop switch. So when the power fails the machine is stopped
and you can record line numbers at least and then shut down.

I doubt that it is common to attempt to machine on standby power, but
I can see
I’m in the process of converting a small medium-duty table router to work with
a LinuxCNC controller. I am duly impressed that such a wealth of technical
information and such a powerful and robust industrial automation tool should be
available to the public, free of charge. Many thanks to all
